FIELD OF THE INVENTION

This invention relates to a configurable roof rack, and in particular, a rack which is configured to be inserted and removable into two cross bars through a hand grip, and further configured to be locked/unlocked with a mechanical key.

BACKGROUND OF THE INVENTION

Regular vehicle racks on the top of vehicles are generally rigid and fixed. It is generally desirable that the vehicle racks be folded or hidden when not in use, since the racks look ugly with a huge structure over the top of vehicles. However, the racks are conventionally not easily removable or foldable from the vehicle's top without help from an expert technician, for example, at a car service station.

Currently, the vehicle racks are also being deployed for advertising purposes with in-built display systems. With the integrated built-in display systems, the vehicle racks have been becoming more complex, and more cumbersome to be folded or hidden by the vehicle owners or drivers. Due to the complex structure of conventional racks, it generally requires involvement of expert technicians to fold, hide, or remove them. Additionally, once the display system-based vehicle racks are installed, the racks are rendered unusable for carrying any luggage. Further, the conventional roof rack crossbars for vehicles are unusable for multiple different racks, and are rather limited to be ideal only for the rack fixed on the vehicle roof.

Presently, there are no solutions to have an integrated display system-based vehicle rack that may also be used like conventional vehicle racks to carry luggage. Also, there are no solutions to hide, fold, or change any configuration of the vehicle racks when not needed.

Additionally, conventional display systems on vehicle roofs include methods for playing electronic content either through direct streaming through a wireless carrier or in-built ad players with hard disk and memory. However, such conventional systems make the electronic content static, without any intelligent mechanism to provide dynamic content to be played therein.

SUMMARY OF THE INVENTION

The present invention seeks to provide a solution to all the above stated problems by providing a configurable roof rack for vehicles with a convenient mechanism to be folded or hidden or removed from public displays by the driver when desired. Specifically, the present invention provides for a mechanical as well as electronic systems for folding/unfolding/removing of the configurable roof rack for vehicles. Further, the present invention provides for providing a mechanism for controlling the electronic content to be displayed on a display system integrated with the configurable roof rack.

The present invention seeks to provide a removable vehicle rack that can be easily removed from the vehicle and stored when not needed. The user can reinstall the rack easily when needed. Further, the present invention seeks to provide a roof rack crossbar that has features that lets the user attach many different kinds of specially designed removable racks onto these crossbars.

The present invention seeks to provide an electronic display attached to a foldable vehicle rack that can be folded and hidden by the driver when not needed. Once folded, the driver can wash the car in any automatic car washes. Drivers can feel not ashamed when the roof rack is hidden at times when they do not need the racks. Versions of the installation could include one or more displays simultaneously on the roof, back, front or any sides of the vehicle or any combinations of therewith.

The content or material to be displayed on this electronic display can be sourced or streamed directly from a wireless carrier using 3G, 4G or 5G or any future similar technologies. Preferably, the content can be streamed through an app on the user's smart phone. Preferably, the electronic display unit can be removed easily and reinstalled easily without any help or expert tools.

The present invention seeks to provide a mobile app driver technology to stream advertisements to electronic displays on vehicles. These electronic displays can be located outside or inside the vehicles. The mobile app streams digital content to the displays using wireless technologies like Wi-Fi, Bluetooth or similar.

According to one embodiment of the present invention, a configurable roof rack for vehicles is provided. The configurable roof rack comprises at least two cross bars arranged parallelly, wherein each of the at least two cross bars comprises a channel. The configurable roof rack further comprises a rack comprising an inner cross bar at each of two opposite sides of the rack, wherein the rack is configured to be fitted into the at least two cross bars by sliding the inner cross bars into the channels of the at least two cross bars, wherein each of the two cross bars comprises a key slot for enabling locking and unlocking of the rack to the at least two cross bars.

FIG. 1 depicts a vehicle 1 having a roof 5, in accordance with the various embodiments of the present invention. In accordance with the various embodiments of the present invention, the configurable roof rack (not shown in FIG. 1) is installed over the roof 5.

While the Figure depicts the vehicle 1 as a car, it may be apparent to a person skilled in the art that the vehicle 1 may include any vehicle capable of possessing a roof generally at its top. For example, the vehicle 1 may include, but not limited to, a car, truck, a roof possessing two-wheeler automobile, a three-wheeler automobile, etc. The roof 5 may be an area of a structure which covers an automobile/vehicle at the top. For example, the roof 5 may be area of the structure between the front and back windshield at the top of a car, or an area of a cover a truck covering the portion carrying passengers and luggage/load. Also, as well known in the art, the area of roof 5 may be used to install a rack or a luggage carrier.

The vehicle 1 may comprise at least two cross bars 3A and 3B that may be fixed to the roof 5 of the vehicle 1 through cross bar clamps (not shown in FIG. 1). As is generally known in the art, the cross bar clamps are affixed to the roof 5 of the vehicle for installation of a rack or a luggage carrier. In a preferred embodiment of the present invention, each of the two cross bars 3A and 3B may be affixed to the roof 5 through two cross bar clamps each. The coupling of cross bar clamps with the two cross bars 3A and 3B may be performed through any well-known mechanism in the art. In accordance with various embodiments of the present invention, the cross bars 3A and 3B may be designed as per the various designs discussed hereinafter, and the configurable roof rack may be installed between the cross bars 3A and 3B.
